node::NodeContext

Synopsis

Declared in <node/context.h>

struct NodeContext;

Member Functions

Name	Description
`NodeContext` [constructor]	Declare default constructor and destructor that are not inline, so code instantiating the NodeContext struct doesn't need to #include class definitions for all the unique_ptr members.
`~NodeContext` [destructor]	Destroy the node context and release its owned members.

Data Members

Name	Description
`addrman`	Address manager tracking known peer addresses.
`args`	Parsed command-line and configuration arguments (memory not owned by this struct).
`background_init_thread`	Background thread that performs the remainder of node initialization.
`banman`	Tracks and persists banned and discouraged peers.
`chain`	Interface giving access to the node's chain state.
`chain_clients`	List of all chain clients (wallet processes or other client) connected to node.
`chainman`	Owns and coordinates the active and background chainstates.
`connman`	Manages the node's peer-to-peer network connections.
`ecc_context`	Owns the process-wide libsecp256k1 signing and verification context.
`exit_status`	Process exit status, set to a failure value when a fatal error occurs.
`fee_estimator_man`	Tracks fee-rate estimates derived from observed transactions.
`indexes`	Active optional block-chain indexes (memory not owned by this struct).
`init`	Init interface for initializing current process and connecting to other processes.
`kernel`	libbitcoin_kernel context
`mempool`	The node's memory pool of unconfirmed transactions.
`mining`	Reference to chain client that should used to load or create wallets opened by the gui.
`mining_args`	Mining options used to create block templates. This value member is an exception to the dependency guidance above because BlockCreateOptions is a minimal dependency. It could be moved to the BlockTemplateCache proposed in bitcoin/bitcoin#33421.
`netgroupman`	Maps peer addresses to network groups for connection bucketing.
`notifications`	Issues blocking calls about sync status, errors and warnings
`peerman`	Drives peer-to-peer message processing and per-peer state.
`rpc_interruption_point`	Hook invoked at interruption points during long-running RPCs.
`scheduler`	Runs deferred and recurring background tasks.
`shutdown_request`	Function to request a shutdown.
`shutdown_signal`	Interrupt object used to track whether node shutdown was requested.
`tor_controller`	Manages the node's Tor hidden service and control connection.
`validation_signals`	Issues calls about blocks and transactions
`wallet_loader`	Interface used to load or create wallets, owned elsewhere.
`warnings`	Manages all the node warnings

Non-Member Functions

Name	Description
`BroadcastTransaction`	Submit a transaction to the mempool and (optionally) relay it to all P2P peers.
`FindCoins`	Look up unspent output information. Returns coins in the mempool and in the current chain UTXO set. Iterates through all the keys in the map and populates the values.
`::AppInitInterfaces`	Initialize node and wallet interface pointers. Has no prerequisites or side effects besides allocating memory.
`::AppInitMain`	Bitcoin core main initialization.
`::CreateUTXOSnapshot`	Helper to create UTXO snapshots given a chainstate and a file handle.
`::EnsureAddrman`	Get the address manager from a node context, asserting it is present.
`::EnsureAnyNodeContext`	Extract the node context from an opaque RPC context, asserting it is present.
`::EnsureArgsman`	Get the argument manager from a node context, asserting it is present.
`::EnsureBanman`	Get the ban manager from a node context, asserting it is present.
`::EnsureChainman`	Get the chainstate manager from a node context, asserting it is present.
`::EnsureConnman`	Get the connection manager from a node context, asserting it is present.
`::EnsureFeeEstimatorMan`	Get the fee estimator from a node context, asserting it is present.
`::EnsureMemPool`	Get the mempool from a node context, asserting it is present.
`::EnsureMining`	Get the mining interface from a node context, asserting it is present.
`::EnsurePeerman`	Get the peer manager from a node context, asserting it is present.
`::InitContext`	Initialize node context shutdown and args variables.
`::Interrupt`	Interrupt threads
`::Shutdown`	Shut down the node, stopping threads and releasing resources.
`::ShutdownRequested`	Return whether node shutdown was requested.
`::StartIndexBackgroundSync`	Validates requirements to run the indexes and spawns each index initial sync thread
